摘要:
对目前地铁工程中通常采用的全高不封闭站台门和封闭站台门以及封闭非封闭转换式等三种站台门的优缺点进行了分析。以乌鲁木齐地铁某地下车站为例，基于气候特点等工程实际情况，对不同站台门方案，从其对应的通风空调系统设备初投资、长期运行能耗、解决区间隧道内的新风量需求、活塞风过站泄压问题等方面进行了综合比选，进而提出乌鲁木齐地铁站台门采用全高非封闭站台门的建议。
Abstracts:
In this paper, the advantages and disadvantages of three metro platform door systems are analyzed, including the full height open platform door, the closed platform door and the closed/open conversion platform door. Taking a metro station in Urumqi City as the example, and fully considering the climate characteristics of the city, different platform door systems are comprehensively analyzed and compared from the angles of initial investment in the ventilation and air conditioning system, the long-term operation energy consumption, the solution to new wind demand in the interval tunnel and the pressure relief of piston wind over the station. Finally, the full height open platform door is recommended for Urumqi metro.
